Oncolytic virus alerts the immune system to attack tumors

A new UC San Francisco study has shown that a cancer-killing virus currently in clinical trials may function as a cancer vaccine - in addition to killing some cancer cells directly, the virus alerts the immune system to the presence of a tumor, triggering a powerful, widespread immune response that kills cancer cells far outside the virus-infected region.
